Increase in medicaid managed care for youth linked to slightly more preventive care

Youth Medicaid enrollment in managed care increased from 65% in 2000 to 94% in 2017, but preventive care coverage fell short of the 80% goal. The study found significant increases in preventive care services in 17 states and decreases in six states, with Tennessee seeing the largest increase and North Carolina the largest decrease.

Stressed-out young oysters may grow less meat on their shells

A study found that early exposure to heat and low oxygen can leave lasting scars on oysters' ability to grow tissue. Oysters invested more in growing their shells than tissue when exposed to the double punch of low oxygen and warmer waters. This could pose a problem for anyone involved in the seafood industry.
